Pingbacks

When user pays or completes an offer, we will send a pingback which will notify your server regarding the transactions.

Pingback request is sent from our servers to your Pingback listener script where we communicate to your server regarding the details about payment transactions so that your server can process the pingback automatically and deliver the goods to the according users.

In your project settings, please input the Pingback URL which is the URL address of your script that processes the pingbacks.

Please add following IP Addresses as authorized IP addresses to access the script:


Pingback Return Value

If you are able to process the requests, please respond back to the Pingback request with OK. If we don’t receive a confirmation message or if the response status code is different from 200, we will send Pingbacks again within 30 minutes and the subsequent retries will happen at 30 minute increments after that.

Pingback Reference

Each pingback has its own reference id which can be identified as the parameter name “ref”.
Reference id is used to track payment transactions. To prevent double crediting and fraudulent users or transactions, we need you to store reference ids to check before you process pingbacks. Please note when you receive pingback :

  • With type=0 : Make sure the reference value is unique. If you have history of same reference id, please do not deliver goods to user twice.
  • With type=2 : Make sure you have a record of reference value with type=0 pingback and take the exact product from user. Please refer Chargeback Pingback for detailed information.
